Évariste Galois, who died in his youth in a duel, is known as one of the greatest mathematicians of all time. Biographers Galois report a tragic and adventurous life, which contains ingredients to a story that certainly would give to write a novel. His theory provided a solution to the question of determining when radicals can solve an algebraic equation. With the formulation of the theory of groups, Évariste Galois changed the mathematics because, given the possibility of opening a promising new front of research, however, died before his work was recognized.
